As a former industrial coatings chemist, I can tell you that "easy pour-on" generally also means "almost good." While I have never (yet) coated an RV roof with any of these products, the nature of the beast is such that a clean roof, good surface prep, and smear -- not simple dump the bucket -- technique is at least as important as the product chosen for the job.
I just bought a 4.7 gallon bucket of Henry Tropicool to do my RV roof, a task I'll be undertaking this spring before camping season. @JBarca, I'm all ears for your experience and tips regarding that product.
Hi, I'm glad to help and share what I have learned, but this will get involved and can be off-topic with what Profdant139 wants to do with his post. Maybe better to start a new post etc. And with that, we need to know your roof membrane, how old it is, and, ideally, some pics of your roof in its current condition. And read over my last response above since you already jumped to Henry 887; what are your expectations?
A former coating chemist, good you will bring a lot to this on making bonds to low surface energy surfaces. And how to do adhesion tests. I look forward to your post. PM me if you decide to create one so I can see it.
Thanks
John
